With a snippet of embedded code, Tidbit could enable websites to tap into visitors’ computers and borrow CPU cycles to mine Bitcoin. In exchange, the sites would remove display advertising for those who opt-in. “We’re hoping that Tidbit can completely replace ad revenue,” wrote Tidbit developer Oliver Song on the Node Knockout site late last year. Tidbit uses the Stratum protocol, which would enable websites to get paid based on total work contributed to the mining pool rather than total Bitcoins mined. But in its current form, Tidbit still isn’t very economical: If people ran Tidbit for a full day, they might each generate around a cent in revenue for a website, but their personal electricity costs would be much higher.
